Anthurium plant named ‘ANTHDUNDAL’

ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHDUNDAL’ particularly characterized by having bright red, cordate spathes, white, short spadix, very rich shoot formation, a very compact plant habit and dark green foliage, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHDUNDAL’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andreanum L., and hereinafter referred to by the variety name ‘ANTHDUNDAL’. The new variety originated from a hybridization made in January 2006 in Bleiswijk, The Netherlands. The female parent is a red Anthurium pot plant designated ‘4110-03’ (unpatented), and the male parent was a red Anthurium plant designated ‘5442-01’ (unpatented).

A single plant was selected from the progeny of the stated cross in February 2007 and has been asexually reproduced repeatedly by tissue culture in Bleiswijk, The Netherlands over a seven-year period. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in Europe on Nov. 19, 2012. ‘ANTHDUNDAL’ has not been made publicly available or sold anywhere in the world more than one year prior to the filing of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands.

-   -   1) Bright red, cordate spathe;     -   2) White, short spadix;     -   3) Very rich shoot formation;     -   4) Very compact plant habit; and     -   5) Dark green foliage.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms, buds and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 45-week old plant grown in a greenhouse in Bleiswijk, The Netherlands in 2014.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHDUNDAL’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 45-week old plants which were planted from tissue culture in 12-centimeter pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in November 2014. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001).

After the spathe is fully             open the peduncle elongates some extra centimeters.         -   Arrangement.—Spathe angle with the peduncle is between 80             degrees and 90 degrees; the spathe stands on a wiry peduncle             about 4.0 cm to 7.0 cm above the foliage.         -   Shape.—Cordate and asymmetrical.         -   Apex.—Acuminate.         -   Base.—Auriculate.         -   Texture.—Shiny and slightly blistered.         -   Margin.—Entire.         -   Size.—Height: 14.0 cm to 20.0 cm (peduncle length at             maturity).

This red color remains approximately 25 to             30 weeks after opening. After this period the spathe is limp             and dies. The small lobes very slowly accumulate some             chlorophyll. The lobes very slowly become green (RHS 146A). -   Peduncle:     -   -   Shape.—Erect.         -   Cross-section.—Round.         -   Length.—14.0 cm to 20.0 cm.         -   Diameter.—0.3 cm to 0.4 cm.         -   Color.—RHS 152C at unrolling of spathe, slowly turning RHS             146B when the spathe matures. -   Flowering time:     -   -   General.—One small rooted untreated tissue culture plant of             2.0 cm tall will flower after 4 to 6 months, depending on             the season, and 3 to 4 blossoms will appear. More blossoms             appear after some additional weeks so that a full flowering             and commercial plant will have 7 to 9 red spathes. Smaller             blossoms may occur on less mature plants. -   Spadix:     -   -   Size.—Length: 2.0 cm to 3.0 cm (depending on flower size).             Width (at apex): 0.5 cm to 0.6 cm. Width (at base): 0.6 cm             to 0.8 cm.         -   Shape.—Columnar.         -   Angle from spadix tip to peduncle.—180 degrees (spadix is in             one line with peduncle).         -   Texture.—When the spathe is unfurling the spadix is smooth.             When the spadix matures, small stigmata protrude. The             stigmata are evenly distributed round the spadix. The spadix             matures from base to top, slowly giving the spadix a             somewhat rough appearance.         -   Color.—Immature: RHS 15B. Mature: RHS 158B.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘ANTHDUNDAL’ differs from the female parent plant ‘4110-03’ (unpatented) in that ‘ANTHDUNDAL’ has a darker green leaf blade with more shine and a darker red spathe color, whereas ‘4110-03’ has a lighter green leaf blade with less shine and a brighter red spathe color. In addition, ‘ANTHDUNDAL’ has a smaller angle between spadix and spathe, whereas ‘4110-03’ has a bigger angle between spadix and spathe.

In addition, ‘ANTHDUNDAL’ has a leaf blade that is less elliptical cordate, whereas ‘5442-01’ has a leaf blade that is more elliptical cordate.

‘ANTHDUNDAL’ differs from commercial variety ‘ANTHEPEDI’ (U.S. Plant Pat. No. 18,644) in that ‘ANTHDUNDAL’ has a smaller spadix width at the base and a smaller mature leaf size than ‘ANTHEPEDI’. In addition, ‘ANTHDUNDAL’ has a long elliptical cordate shaped leaf blade, whereas ‘ANTHEPEDI’ has a cordate shaped leaf blade.

‘ANTHDUNDAL’ differs from commercial variety ‘ANTHCOZAM’ (unpatented) in that ‘ANTHDUNDAL’ has a larger spadix width at the base and a larger mature leaf size than ‘ANTHCOZAM’. In addition, ‘ANTHDUNDAL’ has a long elliptical cordate shaped leaf blade and a red spathe, whereas ‘ANTHCOZAM’ has an elliptical cordate shaped leaf blade and a dark red spathe.
